Product Overview
The MSP430F5529 is a Texas Instruments 16-bit mixed-signal microcontroller based on the MSP430F55xx 16-bit RISC architecture. It supports an operating supply range of 1.8 V to 3.6 V and a system clock up to 25 MHz. The MSP430F5529IPN package is an 80-pin LQFP measuring 12 mm x 12 mm, with 63 I/O pins available on the MSP430F5529 device group.
The device integrates USB 2.0 full-speed support with an integrated PHY, 8 input endpoints, 8 output endpoints, and an integrated 3.3-V and 1.8-V USB power system. Mixed-signal and control resources include a 12-bit ADC with 12 channels, four 16-bit timers, 3 DMA channels, and a hardware multiplier supporting 32-bit operations.
Communication options include USCI_A0, USCI_A1, USCI_B0, and USCI_B1 blocks. These support enhanced UART with automatic baud-rate detection, synchronous SPI, I2C, and IrDA encoder/decoder functions. Based on these integrated peripherals, the MSP430F5529 is suited for USB-connected embedded control, low-power sensing, data acquisition, and serial-interface bridge designs.
